In my actual snake room: humidifier and oil filled heater. Only two things I hadn't seen mentioned yet, lol.
In the area where the rest of the snakes and other reptiles are: computer, various radio controlled aircraft and the parts and tools for the building/maintenance/repair of said aircraft. Thought the workshop content may get moved to the barn this summer sometime.
Edit: Darn it, OWAL beat me to the humidifier, lol.
